Area code 710: us government, not a location
Area code 710 is not a place. NANPA lists it as reserved for the US government, in service since January 1, 1984, so its numbers belong to federal services rather than to a state, a city or a private line.
Free, runs in your browser; nothing is sent. The sample is a sample, not a real line.
Paste your 710 numbers (a mixed list is fine). They are counted here at once; the free checker then gives every number its E.164 form, country and line type, with a file to download.
By continuing you agree to our Terms and Privacy Policy.

What a 710 number is for
710 numbers are not issued to businesses or the public, so a 710 row in a contact list is almost certainly a mistake, a test entry or a government service line. Google's libphonenumber data reads it as "not a recognised type".
Flag these rows with a bulk validator and leave them out of calling and SMS campaigns.

The bulk phone number validator tags every row with its type (toll-free, premium, mobile or landline) and writes it in E.164, free.
Next step
The numbering plan says what a range is for, not who answers.
