T-Mobile phone numbers: carrier and line type lookup
T-Mobile is one of the three national US wireless carriers and merged with Sprint in 2020. Numbers on T-Mobile are mobile lines.

- ✓Line type: mobile, landline, VoIP or toll-free, labeled per number.
- ✓Valid or dead, so disconnected numbers are dropped before you dial or text.
- Metro by T-Mobile numbers are also mobile.
Numbers can be ported between carriers, so a carrier check is a snapshot of where the number is now. Carrier names are shown as they appear in carrier data and can be formatted differently from the brand name.

Questions
How do I know if a number is on T-Mobile?
Run it through a carrier lookup. TrueSearch returns the carrier name for each number from live carrier data, so ported numbers show the carrier they are on now, not the one that first held the prefix.
Is a T-Mobile number a cell phone?
Usual line type: Mobile. TrueSearch labels every number as mobile, landline, VoIP or toll-free, so you do not have to guess from the carrier name.
Can I check a whole list at once?
Yes. Upload a CSV or Excel file; each row comes back with valid, line_type and carrier columns. Starter is $97/month for 5,000 numbers after a 7-day free trial.
