PortNumbersForSale is a digital goods website that sells US mobile phone number porting details. After purchase, users receive a phone number, account number, and PIN, which can be used to port the number into another wireless carrier account. It is not an email marketing, bulk SMS, voice calling, or IM communications platform; its core value is providing pre-activated mobile numbers that can be used for number porting.
Based on the site text, the currently available carriers include Verizon Wireless, T-Mobile, and Boost Mobile, all marked as MOBILE lines, with area code selection available at checkout. Delivery is via email. The site also provides Phone / WhatsApp / Text contact channels, but does not offer an SMS API, email API, voice lines, or instant messaging integrations. Its “communications” capability is mainly the delivery of porting credentials, rather than message delivery or outreach.
Pricing is relatively transparent: the Verizon page lists a price of $14, while T-Mobile and Boost Mobile are $13, with all three showing an original price of $15. Payments are in USD via Stripe. The site claims delivery usually takes 1–5 minutes, and the homepage highlights “<5 Min Delivery,” “100% Accuracy Rate,” and “100K+ Numbers Delivered.” However, the terms of service also state that delivery times are only estimates and may be affected by carrier availability and system load; a small number of orders may take several hours.
The site emphasizes that number porting is a right protected under FCC rules, and requires users to be at least 18 years old and to use the service only for lawful purposes. Unauthorized porting, fraud, identity theft, and SIM-swapping are prohibited. It also clearly states that it is not a carrier, MVNO, or agent of any carrier, and does not guarantee that porting will succeed with all carriers or promotional scenarios. Numbers are typically valid for about 5 days. As digital goods, sales are generally non-refundable; replacement or refund may only be possible in cases such as incorrect credentials, numbers not meeting the stated promotional eligibility, or non-delivery within 24 hours.
The advantages are a simple process, clear pricing, fast delivery, and a replacement/refund mechanism for credential errors. The downsides are that coverage is limited to certain US carriers, the usage window is short, successful porting is not guaranteed, and there are no APIs, bulk management tools, or enterprise-grade SLAs. It is best suited to individual users who understand US carrier port-in promotion rules and need to quickly obtain a single porting number or a small number of numbers.
The text does not provide information on access speed from mainland China, payment card support, or localization, so its accessibility from China is unknown. If users in China need compliant communications APIs or number services, they may want to compare international number/API platforms such as Twilio and Plivo based on their actual requirements, or use official US carrier and MVNO channels directly.
