How many prefixes does area code 401 have?
578 NXX prefixes are currently active per NANPA records (of a theoretical maximum of 792 assignable).
What does "pooled" mean in this table?
A pooled prefix is split into ten 1,000-number blocks that can be assigned to different carriers, so numbers sharing the prefix may be served by different companies. 420 of 401's prefixes are pooled.
Can I tell a number's current carrier from its prefix?
