How numbers in the United States are built
A US number is a three-digit area code followed by a seven-digit number. From abroad always dial the area code; there is no trunk prefix to drop.
A number in the United States is the country code +1 followed by a national number of 10 digits. The trunk prefix, where there is one, is dropped after the code.
Written locally as (201) 555-0123, an example mobile number in the United States is dialed as +1 201 555 0123 from abroad.
There's no leading digit to leave out: dial the full local number after the country code.
Why a call to the United States fails to connect
- Leaving out 00 (or +): without it your carrier reads 1 as the start of a number in Portugal, not as a country code.
- A wrong number of digits: a number in the United States has 10 digits after +1.
Best time to call
New York (Eastern Time) is 4 h behind Portugal. When it is 12:00 in Portugal, it is 08:00 in New York.
For most of the year the gap is the same. It shifts by an hour for a few weeks in spring and autumn, between the two countries' clock changes (dates below).
Portugal changes its clocks for daylight saving, so its offset moves between UTC and UTC+1 during the year.
Portugal moves its clocks on March 29 and October 25.
Most of the United States changes its clocks on March 8 and November 1; Hawaii and most of Arizona do not.
The 48 contiguous states use four time zones: Eastern (New York), Central (Chicago), Mountain (Denver) and Pacific (Los Angeles). Pacific time is 3 h behind Eastern, so the table shows both ends: New York and Los Angeles.
Where a country spans several time zones, this page uses its main one, so the real gap can differ by a few hours.
The weekend in the United States is Saturday and Sunday.
