What It Is

Grizzly SMS is a virtual phone number platform for receiving SMS verification codes. Its core use case is providing one-time numbers for activating online services such as WhatsApp, Telegram, Google/Gmail/YouTube, Facebook, Amazon, OpenAI/ChatGPT, Instagram, TikTok, and PayPal. The site shows a service list of up to 2,420 items, with inventory and pricing displayed by country and service.

Core Capabilities

In terms of channels, the platform mainly provides SMS-only virtual numbers and does not support voice calls. Standard one-time numbers are typically valid for 20 minutes, can only be used for the selected service, and usually receive only one SMS; a small number of services support multiple verification codes, and number rental options are also available. Regional coverage is very broad, including many countries and regions across Europe, North America, Southeast Asia, the Middle East, Africa, Latin America, Hong Kong, China, and more. However, Russian numbers are not offered, and access from Russia is restricted. On the API side, the documentation is relatively complete, supporting number acquisition, activation status checks, balance queries, pricing, active activation lists, and more. It is also compatible with the sms-activate API, making it suitable for automated registrations and bulk purchasing.

Pricing

Grizzly SMS uses a prepaid balance model, with a minimum top-up of $3. Fees vary dynamically by country and service. Example prices shown on the site indicate that virtual numbers from Canada, Vietnam, and the United States can cost as little as a few dozen cents, while numbers from Australia, Ireland, Gibraltar, and other regions can range from the teens to around thirty dollars. According to the official explanation, charges are only applied to numbers that receive a verification code. If no SMS is received, the activation can be canceled, with refunds usually processed within about 20 minutes.

Pros and Cons

The advantages are its very broad coverage of services and countries, wide pricing range, API support for programmatic integration, and communication channels for wholesale buyers. The drawbacks are also clear: the platform does not officially guarantee 100% delivery, and popular platforms such as Telegram and WhatsApp may require multiple attempts; inventory is only an estimate, so popular numbers may fail to be obtained; and the numbers are highly disposable, making them unsuitable for long-term account security maintenance.

Who It’s For

It is better suited for developer automation testing, bulk registration, CPA/traffic arbitrage, temporary verification code reception, and teams that need number pools across multiple countries. It is not suitable for businesses that need to hold numbers long term, receive phone calls, reliably recover accounts, or perform strict compliance-based identity binding.

Access from China

The crawled content does not provide information on availability from mainland China, so the access status from China is unknown.
