US SMS Verification Numbers
American platforms verify more than the code: they score the line type, the prefix history and the network you connect from. That is why a real US carrier number passes where a virtual number silently fails.
sms688 rents US T-Mobile SIM numbers for 2-30 days with renewal, covering 100+ services from OpenAI and Google Voice to banks and marketplaces.
Codes usually arrive in under a minute and sync automatically to your SMS center. If a code never arrives, swap the number instead of paying twice.
Open the marketContact supportWhat you get

How it works
- Pick the service — Choose the platform you need to verify — the market lists tiers and live stock.
- Choose a tier — 2-10 days for one-time verification; 11-30 days for accounts you keep.
- Verify — Enter the number on the platform and read the code in your private link.
- Renew or swap — Renew before expiry, or swap the number if the platform refuses it.
US number types: carrier, VoIP and free pools
Three things get called a "US number" and only one of them behaves like a phone. Carrier numbers come from a mobile network operator such as T-Mobile; they receive short codes, bank alerts and platform messages, and they survive a device change. VoIP numbers are issued by internet telephony providers - they work for a phone call, but a growing list of platforms reject the range outright. Free public pools are shared numbers published on the web; thousands of people have already used them, so the platform either refuses the number or the code is read by somebody else.
sms688 rents carrier lines only. Every number in the marketplace is tagged with its operator and prefix, so you can see the type before you pay, and the per-prefix success rate is published instead of hidden behind a marketing claim.
Which platforms accept which number
Strict: banks, brokerages, payment apps and AI services (OpenAI, Codex, Claude) screen number type and usage history, so they need a fresh carrier line. Medium: marketplaces and travel apps such as Vinted, Amazon, Uber or Booking usually accept a carrier number and only complain when the number was used before. Loose: messaging apps accept almost anything but still flag numbers that are already tied to an account.
That is why the same rented number can be perfect for one target and useless for another: match the tier and the prefix to the platform you are verifying, and keep the line for the follow-up check.
