The towns inside area code 956
Area code 956 is not a city code. It covers 35 separate rate centres — billing areas, each its own local calling zone. The largest of them are named in the table below.
That matters twice over. A call between two 956 numbers is not necessarily a local call, because they can sit in different rate centres. And a code this wide narrows a subscriber to a region rather than a town.
Texas is split across 28 area codes — 346, 832, 469, 210, 956, 512 and others. By allocated blocks 956 is the 5th largest of them, holding 5% of the Texas total.
Where 956 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Brownsvl and Rigrandecy are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.
