I.
This case involves a facial challenge to North Dakota Century Code Chapter 51-28 (the “Act”), which prohibits certain telephone solicitations of North Dakota residents who register with the state’s “do-not-call” list. Plaintiffs are nonprofit organizations who rely on professional charitable solicitors for then’ fundraising.
The Act exempts telephone solicitations made by charitable organizations if “the telephone call is made by a. volunteer .or employee of the charitable organization” and the caller makes specified disclosures. N.D. Cent.Code § 51-28-01(7) (2003).2 The Act thus distinguishes between “in-house” charitable solicitors and professional charitable solicitors. Further, the Act’s restrictions apply only to telephone solicitation. See id. Under the Act, a charity may hire an outside agency to call registrants to advocate the charity’s message, but that agency may not solicit the registrant to donate funds.
The district court invalidated a portion of the Act as a content-based regulation that failed strict scrutiny. The district court also awarded attorney’s fees under 42 U.S.C. § 1988. North Dakota appeals from the invalidation of the Act, and the parties cross-appeal the award of attorney’s fees. We reverse.
II.
court’s grant of judgment on the pleadings as to the unconstitutionality of the Act. Potthoff v. Morin, 245 F.3d 710, 715 (8th Cir.2001). Because professional charitable solicitation is fully protected speech, see Riley v. Nat’l Fed’n of the Blind of North Carolina, Inc., 487 U.S. 781, 796, 108 S.Ct. 2667, 101 L.Ed.2d 669 (1988), we begin our analysis by determining whether the North Dakota regulation is content neutral or content based.
The principal inquiry in determining content neutrality is whether the government has adopted a regulation of speech because of disagreement with the message the speech conveys. Ward v. Rock Against Racism, 491 U.S. 781, 791, 109 S.Ct. 2746, 105 L.Ed.2d 661 (1989). “A regulation that serves purposes unrelated to the content of expression is deemed neutral, even if it has an incidental effect on some speakers or messages but not others.” Id. Regulation of expressive activity is content neutral if it is justified without reference to the content of the regulated speech. Id.
Applying these principles to North Dakota’s statute, it is evident that the Act is content neutral. First, North Dakota has not distinguished between professional and in-house charitable solicitors because of any disagreement with the message that would be conveyed, for the message would be identical regardless of who- conveyed it. Second, the regulation can be justified without reference to the content of the regulated speech, for North Dakota’s interest is in protecting residential privacy.
Although the Act appears to make subject matter distinction between advocacy and solicitation, a regulation that distinguishes between speech activities likely *597to produce the consequences that it seeks to prevent and speech activities unlikely to have to those consequences “cannot be struck down for failure to maintain ‘content neutrality.’ ” Hill v. Colorado, 530 U.S. 703, 724, 120 S.Ct. 2480, 147 L.Ed.2d 597 (2000). As the Tenth Circuit observed in reviewing the commercial solicitation restrictions of the national do-not-call registry, the interest in residential privacy “is not limited to the ringing of the phone; rather, how invasive a phone call may be is also influenced by the manner and substance of the call.” F.T.C. v. Mainstream Mktg. Servs., Inc., 345 F.3d 850, 855 (10th Cir.2003) (per curiam). Because solicitation may reasonably be viewed as more invasive than advocacy, we conclude that the Act is a content-neutral regulation. See United States v. Kokinda, 497 U.S. 720, 110 S.Ct. 3115, 111 L.Ed.2d 571 (1990) (plurality of the Court upholding Postal Service regulation distinguishing between solicitation and advocacy); Nat’l Fed’n of the Blind of Arkansas, Inc. v. Pryor, 258 F.3d 851, 855 n. 3 (8th Cir.2001). (rejecting the charity’s argument that the regulation was content based because it regulated only speech that solicits charitable contribution or commercial sales).
III.
of professional charitable solicitation is derived from Village of Schaumburg v. Citizens for a Better Environment, 444 U.S. 620, 636, 100 S.Ct. 826, 63 L.Ed.2d 73 (1980). Although the Supreme Court has not specified whether the Schaumburg test is an intermediate scrutiny review of a content-neutral regulation, we have interpreted it as such. See Pryor, 258 F.3d at 854.
We observed in Pryor that the Schaum-burg test is “obviously very similar” to the time, place, and manner test enunciated in Ward. Id. at 855. We then considered: (a) whether the State had a sufficient or “legitimate” interest; (b) whether the interest identified was “significantly furthered” by a narrowly tailored regulation; and (c) whether the regulation substantially limited charitable solicitations. Id. at 855-56.
A.
The first question under Pryor is whether the State has a sufficient or legitimate interest. We have held that residential privacy is a “significant” government interest, particularly when telemarketing calls “are flourishing, and becoming a recurring nuisance by virtue of their quantity.” Van Bergen v. Minnesota, 59 F.3d 1541, 1555 (8th Cir.1995). See also Frisby v. Schultz, 487 U.S. 474, 484, 108 S.Ct. 2495, 101 L.Ed.2d 420 (1988) (“The State’s interest in protecting the well-being, tranquility, and privacy of the home is certainly of the highest order in a free and civilized society.”). The rationale underlying the North Dakota regulation falls within this significant interest.
B.
We next consider whether North Dakota’s regulation is narrowly tailored. “The requirement of narrow tailoring is satisfied so long as the regulation promotes a substantial interest that would be achieved less effectively absent the regulation and the means chosen does not burden substantially more speech than is necessary to further the [state’s] content-neutral interest.” Krantz v. City of Fort Smith, 160 F.3d 1214, 1219 (8th Cir.1998) (citations omitted); Ward, 491 U.S. at 799, 109 S.Ct. 2746. When a content-neutral regulation does not entirely foreclose any means of communication, it may satisfy the tailoring requirement even though it is not the least restrictive or least intrusive means of serving the *598statutory goal. Hill, 530 U.S. at 726, 120 S.Ct. 2480.
North Dakota’s goal of ensuring residential privacy would be achieved less effectively if the legislature exempted professional charitable solicitors from the Act. Seeking to balance the interest of callers against the privacy rights of subscribers, the legislature distinguished between in-house and professional charitable solicitors. North Dakota contends that the distinction is based upon the sheer volume of calls because “[a] charity using paid'professional telemarketers is typically able to dial substantially more residential telephone numbers than if the charity used its own volunteers and employees.” Appellant’s Brief at 11. In this facial challenge, we are reluctant to second-guess the North Dakota Legislature’s judgment that professional charitable solicitors intrude more regularly on residents’ privacy than volunteers or employees and that the Act is a necessary means of enabling its citizens to halt these intrusions. See Pryor, 258 F.3d at 856 (giving deference to the state in a facial challenge to the state’s telephone solicitation regulations).
The Fourth Circuit recently upheld the Federal Trade Commission’s (FTC’s) charity-specific- do-not-call provision. Nat’l Fed’n of the Blind v. F.T.C., 420 F.3d 331, 341 (4th Cir.2005). Like the statute at issue here, the FTC regulation applied to professional charitable solicitors and exempted in-house or volunteer solicitors. The court held that the regulations struck an appropriate balance between “[t]he rights of charities and telefunders to communicate with potential donors” and “the right of those donors to enjoy residential peace.” Id. at 349-50. Accordingly, the court held that the provision was “a permissible governmental response to a legitimate and substantial public concern.” Id. at 350. We find the Fourth Circuit’s analysis persuasive, and we join in it in upholding the distinction between professional charitable solicitors and in-house charitable solicitors:
The appellees argue that this distinction renders the Act underinclusive because a ringing phone disrupts residential privacy whether the caller is a volunteer or a professional. They claim that the exemption of in-house charitable fundraisers demonstrates that the Act is not related to residential privacy. Although exceptions from an otherwise legitimate regulation of speech may undermine the government’s reasons for the regulation, City of Ladue v. Gilleo, 512 U.S. 43, 52, 114 S.Ct. 2038, 129 L.Ed.2d 36 (1994), we do not perceive that to be the case here. North Dakota’s do-not-call statute does not give one side of a debate an advantage over the other, but rather it reduces the total number of unwelcome telephone calls to private residences. “[T]he validity of the regulation depends on the relation it bears to the overall problem the government seeks to correct, not on the extent to which it furthers the government’s interest in an individual case.” Ward, 491 U.S. at 801, 109 S.Ct. 2746. In the case before us, the overall problem is the intrusion on residential privacy caused by unwanted telephone solicitation. We are satisfied that the Act furthers the state’s interest in preserving residential privacy.
Additionally, the Act does not burden more speech than is necessary to further the State’s interest in residential privacy. The place to which a regulation applies must be taken into account in determining whether a statute is narrowly tailored. Hill, 530 U.S. at 728, 120 S.Ct. 2480. As the Court pointed out in Frisby v. Schultz, “[A] special benefit of the privacy all citizens enjoy within their own walls, which the State may legislate to protect, is an ability to avoid intrusions.” 487 U.S. at
*599484-85, 108 S.Ct. 2495. Accordingly, we find it relevant that the Act applies only to personal residences. Further, a content-neutral and viewpoint-neutral opt-in provision like the one here limits the degree of government interference with First Amendment interests. See Rowan v. United States Post Office Dep’t, 397 U.S. 728, 738, 90 S.Ct. 1484, 25 L.Ed.2d 736 (1970) (statutory scheme giving sole discretion to private citizen to determine whether material was “erotically arousing or sexually provocative” avoided “possible constitutional questions that might arise from vesting the power to make any discretionary evaluation of the material in a government official”); see also Mainstream Mktg. Seros., Inc. v. F.T.C., 358 F.3d 1228,1242 (10th Cir.2004) (finding the national do-not-call registry narrowly tailored because “it restricts only calls that are targeted at unwilling recipients”). Although the opt-in nature of the Act is not dispositive, we find it important that the Act’s restriction is triggered only when a resident joins the do-not-call registry. Absent this affirmative private action, there is no restriction on a charity’s use of professional charitable solicitors. Because the Act prohibits only calls to unwilling residents in their homes, we hold that the Act is narrowly tailored to serve the government’s substantial interest in protecting residential privacy.
Finally, the Act need not be the least restrictive means to satisfy the tailoring requirement. Hill, 530 U.S. at 726, 120 S.Ct. 2480. Although exempting all charitable solicitations from the Act or requiring a charity-specific do-not-call list would be less restrictive than North Dakota’s regulation, we are not convinced that the existence of these options renders the Act unconstitutional. Because this narrowly drawn, content-neutral statute does not entirely foreclose any means of communication, we are satisfied that the Act is sufficiently tailored to pass constitutional muster.
C.
We turn, then, to the final consideration under Pryor, whether North Dakota’s regulation substantially limits charitable solicitations. We conclude that it does not. The Act prohibits calls to the homes of residents who have chosen not to receive calls from professional charitable solicitors. The Act does not foreclose all means of charitable solicitation directed at these residents. Employees or volunteers may solicit funds from all North Dakota residents, and professionals may solicit funds from residents who have not registered with the state’s do-not-call list. Further, the charities may launch fundraising campaigns through the mail or in person. Although the Act restricts charitable solicitation, it leaves open several alternative channels of communication. Accordingly, we conclude that the Act does not substantially limit charitable solicitation.
IV.
Appellees argue that the Act is overbroad because it “makes no legitimate effort to distinguish telemarketing calls affecting residential privacy and innocuous speech” and it prevents unknown charities from soliciting North Dakota residents who have registered with the state’s do-not-call list. Appellees’ Brief at 26. “For a statute to fail on overbreadth grounds, ‘there must be a realistic danger that the statute itself will significantly compromise recognized First Amendment protection of parties not before the Court.’ ” Pryor, 258 F.3d at 856 (quoting City Council v. Taxpayers for Vincent, 466 U.S. 789, 801, 104 S.Ct. 2118, 80 L.Ed.2d 772(1984)). The North Dakota statute does not present that danger. When North Dakota citizens *600register on the do-not-call list, they choose to exclude telephone solicitation from their homes. The registrants have decided that the Act’s banned phone calls intrude on their residential privacy. Further, unknown charities will be treated the same as the appellees. Appellees simply cannot support their claim that the Act impermis-sibly curtails the First Amendment rights of parties not before this court.
Conclusion
In holding that the Act does not run afoul of the First Amendment, we echo Judge Wilkinson’s observations:
In reviewing these rules, we have no wish to exaggerate. Not every home is a “peaceable kingdom.” And it is not the end of the world when a family receives an abandoned call or a late night call that interrupts its evening. But it is one more small strain that families already stressed by twenty-first century life are forced to endure. Our Constitution does not require that we add to family burdens by forbidding even the most reasonable and minor restrictions on telemarketing practices .... Our Constitution does not prevent the democratic process from affording the American family some small respite and sense of surcease.
Nat’l Fed’n of the Blind v. F.T.C., 420 F.3d at 343, 351.
North Dakota’s narrowly tailored do-not-call statute significantly furthers the state’s interest in residential privacy. The Act does not substantially limit charitable solicitations and is not unconstitutionally overbroad.
The judgment is reversed, and the case is remanded to the district court with direction to dismiss the complaint. Likewise, the order awarding attorney’s fees is reversed.
. The Act also exempts calls made with a resident’s prior written consent; by or on behalf of any person with whom the resident has an established personal or business relationship; by or on behalf of pollsters unless the call is made through an automatic dialing-announcing service; by individuals soliciting without the intent to complete the solicitation on the phone but who will follow up with a face-to-face meeting; and by or on behalf of a political party, candidate, or other group with a political purpose.
