Parse the number

Normalise the number first. People write the same number many ways, and every later step works better with the international E.164 form (+12025550123).

ot run osintverse-community/phone-parse --phone "+1 202-555-0123"
ot run osintverse-community/phone-parse --phone "(202) 555-0123" --region US

Use --region for numbers written without a country code. The tool runs offline on Google's libphonenumber data and returns:

Field Meaning
valid / possible Whether the number fits the country's numbering plan
e164, international, national The standard ways to write it; search for all of them
region, location Country and, for fixed lines, the area the range covers
carrier The carrier the range was assigned to (see the porting note in scope)
line_type mobile, fixed_line, voip, toll_free, premium_rate…
time_zones Useful when matching activity times

Tip

voip numbers are cheap to get and common for throwaway accounts. A fixed_line number with an area points to a place, which mobile numbers do not.

phoneinfoga gives a second view with its own number scan:

ot run osintverse-community/phoneinfoga --phone "+12025550123"

Next: accounts and mentions.
