Understanding *67 and Caller ID Blocking in Canada

Understanding *67 and Caller ID Blocking in Canada

Many businesses wonder whether dialing 67 before a number will block their caller ID when making calls from Canada. This vertical service code is widely recognized in North America for suppressing outgoing caller ID information, but its functionality and legal treatment can vary by country and carrier. For companies like CallMyCustomers, which operates from Halifax, Nova Scotia and places outbound calls to U.S. customers, understanding how 67 functions in Canada is essential for maintaining compliance and transparency in customer outreach.

In Canada, the Canadian Radio-television and Telecommunications Commission (CRTC) does not prohibit the use of caller ID blocking services like 67 for personal or business calls. However, the CRTC requires that telemarketers transmit accurate caller ID information when making commercial calls, as part of its Unsolicited Telecommunications Rules. This means that while 67 may technically prevent a number from displaying on a recipient’s phone, using it to conceal identity during telemarketing calls could violate CRTC guidelines if it results in misleading or anonymous calling practices. Businesses must ensure that any use of caller ID blocking does not obstruct the ability of consumers to identify the source of the call, especially when combined with other compliance obligations like honoring the National Do Not Call List.

When making calls from Canada to the United States, businesses must also consider U.S. regulations enforced by the Federal Communications Commission (FCC) and the Federal Trade Commission (FTC). The FCC mandates that telemarketers display their phone number and, if possible, their company name on caller ID to promote transparency. Intentionally blocking caller ID when calling U.S. consumers may be deemed a deceptive practice under the Telemarketing Sales Rule, potentially leading to penalties. Since the TCPA and related rules require clear identification, relying on *67 to mask origin could undermine compliance efforts, particularly for businesses executing reactivation campaigns where trust and recognition are central to success.

For CallMyCustomers, which manages customer reactivation campaigns for U.S.-based service businesses from its Canadian headquarters, this dual-jurisdiction reality means caller ID handling must align with both Canadian technical capabilities and U.S. consumer protection standards. Rather than using 67 to obscure identity, the service emphasizes transparent, permission-based outreach where clients approve all messaging and calls are made using identifiable numbers. This approach supports compliance with both CRTC expectations and U.S. telemarketing laws, ensuring that reactivation efforts remain respectful, traceable, and effective—especially when reaching customers who may have forgotten a business within approximately 12 months, as noted in industry insights.

• Ensure caller ID displays accurate business information when calling U.S. consumers to comply with FCC transparency rules
• Avoid using 67 for telemarketing calls if it prevents identification, as this may violate CRTC Unsolicited Telecommunications Rules
• Honor opt-out requests immediately and maintain accurate call records to meet both Canadian and U.S. compliance standards

How CallMyCustomers Handles Caller ID for US Campaigns from Canada

Many businesses wonder if using 67 to block caller ID is an option when reaching out to customers, especially when managing campaigns across borders. For CallMyCustomers, which operates from Halifax, Nova Scotia to serve U.S.-based service businesses, transparency in caller identification is a core part of its compliance-first approach. The company does not use caller ID blocking, masking, or modification techniques like 67 in any of its outreach campaigns targeting U.S. consumers or businesses.

This practice aligns with both U.S. Telephone Consumer Protection Act (TCPA) requirements and Canadian Radio-television and Telecommunications Commission (CRTC) guidelines, which emphasize clear caller identification as a foundation of ethical telemarketing. While the provided research does not contain specific data on *67 usage rates in Canada or caller ID blocking prevalence, it does highlight that U.S. TCPA regulations now require businesses to honor opt-out requests within a 10-business-day window—a standard CallMyCustomers follows rigorously across all communication channels. Maintaining visible caller ID supports this compliance by ensuring recipients can easily identify the caller and exercise their right to opt out without confusion.

CallMyCustomers’ commitment to transparency extends beyond regulatory adherence to reflect its relationship-first reactivation model. Every call is made using a verifiable business-associated number, allowing recipients to recognize the call as legitimate and tied to a prior customer relationship. This approach reinforces trust, reduces the likelihood of calls being flagged as spam, and supports higher engagement rates—consistent with industry insights showing that reactivating a known customer is significantly more cost-effective than acquiring new ones. By avoiding caller ID blocking entirely, the company ensures its campaigns remain permission-based, auditable, and respectful of consumer preferences, whether the recipient is in Canada or the United States. This disciplined handling of caller ID is one way CallMyCustomers upholds its promise to run campaigns only as approved by the client, with full transparency at every step.

Compliance Best Practices for Reactivation Campaigns Across Borders

Reactivate customers across borders with confidence by aligning your outreach with compliance standards in both the U.S. and Canada. Since CallMyCustomers operates from Halifax, Nova Scotia, and serves U.S.-based service businesses, understanding cross-border telemarketing rules is essential for maintaining trust and avoiding regulatory risks. While the provided research does not cover Canadian-specific caller ID practices like *67 usage, it does highlight critical U.S. TCPA updates that inform broader compliance strategies. For instance, the FCC now requires businesses to honor opt-out requests within 10 business days, effective April 11, 2025, reinforcing the need for prompt and transparent response mechanisms in any reactivation campaign. This standard aligns closely with Canadian expectations under the Canadian Radio-television and Telecommunications Commission (CRTC), where timely opt-out processing is also mandated under the Unsolicited Telecommunications Rules.

To ensure compliance when working with Canadian-based providers like CallMyCustomers, U.S. service businesses should prioritize three core practices: securing verifiable consent before outreach, maintaining accurate caller ID transparency, and rigorously honoring both the U.S. National Do Not Call Registry and Canada’s National Do Not Call List (DNCL). Consent must be clear, informed, and documented—especially when reactivating customers who may have interacted with your business months or years ago. CallMyCustomers supports this by requiring client approval of all scripts and messages before deployment, ensuring that every communication reflects your brand’s voice and compliance standards. Additionally, the service routes replies directly into your booking process, allowing real-time handling of opt-out requests and inquiries, which helps meet the 10-business-day optoot window now enforced under updated TCPA rules.

Implementing these safeguards not only reduces legal exposure but also strengthens customer relationships by demonstrating respect for privacy and preferences. A recent industry analysis notes that the U.S. home services market reached a $657 billion total addressable market, underscoring the significant revenue potential in reactivation efforts when done correctly. Meanwhile, U.S. construction job openings hit 440,000 in April 2023, reflecting ongoing demand for skilled tradespeople—making customer retention even more vital in competitive local markets. By grounding your reactivation strategy in consent, transparency, and list hygiene, you turn past customers into booked work without compromising compliance. This approach ensures your outreach remains effective, ethical, and aligned with evolving telemarketing standards on both sides of the border.
