What It Is

My Old Number is an independent information resource site. Its core purpose is not to provide email, SMS, or voice messaging services, but to help users understand the recycling timeline for disconnected U.S. mobile numbers, carriers’ “win-back/retention” recovery processes, and possible account-recovery approaches when an old number tied to SMS 2FA causes account lockout. The site clearly states that it is not affiliated with AT&T, Verizon, or T-Mobile, and that it cannot access carrier databases.

Core Capabilities and Communication Scope

In terms of channels, it mainly deals with mobile numbers, voice/SMS numbers, and SMS 2FA scenarios, but it does not provide bulk SMS, email delivery, voice calling, or IM interfaces. Its coverage is clearly U.S.-focused, highlighting number recycling windows such as 45–60 days for AT&T, 30–50 days for Verizon, and 45–90 days for T-Mobile. It also provides customer service numbers, department names, and suggested directions for communication scripts. For numbers disconnected within the past 30 days, the site recommends contacting the original carrier immediately to attempt reactivation; between 30 and 60 days, escalation to Tier 2 support or a Win-Back team may be needed; after 60 days, the focus shifts more toward account-level 2FA bypass or recovery.

Pricing and Integration

Pricing information is limited. The content indicates that the site offers free materials, an email-delivered checklist, and is supported by Google AdSense advertising. It also offers an optional Recovery Guide PDF, but does not disclose the exact price, payment methods, or refund policy. On the API and integration side, there are no SMS APIs, email APIs, SDKs, Webhooks, or enterprise system integration capabilities, so it cannot be assessed as a communications platform in terms of technical delivery.

Compliance, Pros and Cons, and Target Users

Compliance messaging is one of the site’s stronger areas: it mentions CPNI protections, explains that carriers will not disclose the current holder of a number, and warns that harassing the new number owner or using social engineering is illegal. Its strengths are a focused use case, clear step-by-step guidance, and coverage of common issues such as Google Voice, iMessage, number porting, and toll-free numbers. Its limitations are that it can only provide guidance and cannot guarantee number recovery; coverage is mainly limited to the U.S.; PDF pricing is not transparent; and details on how it verifies real-time policy changes are lacking.

Access from China and Alternatives

Access from mainland China is not mentioned in the source content, so it is considered unknown. Since the relevant carriers and regulations are U.S.-based, the site is only useful for Chinese users who have a U.S. number or accounts on U.S. platforms. Alternatives include contacting the original carrier’s customer support directly, reviewing FCC consumer resources, checking the Google Voice Help Center, and using the account recovery processes provided by banks, email providers, and social platforms themselves.
