How to read a number

+17875550123

+1Country code
Puerto Rico.
787Area code
Puerto Rico is a US territory using the North American Numbering Plan (+1); NANPA's area code list shows two codes in service, 787 and 939, shared by mobiles and landlines, so the number alone doesn't tell you it's a mobile. Numbers are managed under US rules and are portable, so the number doesn't identify the operator either.

Carriers & prefixes

Mobile prefixes by carrier.

Number portability applies — a prefix only shows the original carrier.

Porting rules in full

Numbers are portable under the US Federal Communications Commission's rules, including between mobile and landline. Federal regulation 47 CFR 52.35 requires simple landline-to-landline and intermodal (mobile–landline) ports to be completed within one business day (four for non-simple ones); it doesn't set a mobile-to-mobile deadline, so none is given here.
