Area code 619
Area code 619 covers San Diego. We hold 6,005 allocated blocks for it across 17 rate centres, split 55% mobile, 33% landline and 12% VoIP.
The other area codes laid over 619
Area code 619 does not have San Diego to itself. 1 other code — 858 — serves the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
8584,668 blocks, 19 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 619 number and a 858 number from the same street can report different line types. Filtering San Diego by area code needs all 2 of them.
619 is not confined to San Diego itself: its blocks sit across 17 rate centres, named in the table below.
California is split across 40 area codes — 657, 707, 559, 209, 530, 619 and others. By allocated blocks 619 is the 12th largest of them, holding 3% of the California total.
Where 619 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Sndg Sndg and Nationalcy are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, T-Mobile USA, Inc., has 13% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 619 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Common questions
Where is area code 619?
Area code 619 covers San Diego. It is not the only code there: 858 is an overlay on the same rate centres, so a San Diego number can start with any of them.
Is a 619 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 619 the split runs 55% mobile, 33% landline and 12% VoIP, so mobile is the most likely single answer.
Which carriers hold 619 numbers?
The largest holders are T-Mobile USA, Inc., AT&T Wireless, T-Mobile Usa, Inc.. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 619 numbers are there?
The code holds 6,005 allocated blocks in our copy of the numbering plan. A block is 1,000 or 10,000 consecutive numbers depending on how deeply it has been pooled, so 619 covers on the order of 6,005,000 possible numbers — most of which have never been issued to anyone.
