The other area codes laid over 708
Area code 708 does not have La Grange to itself. 1 other code — 464 — 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.
4641,143 blocks, 24 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 708 number and a 464 number from the same street can report different line types. Filtering La Grange by area code needs all 2 of them.
708 is not confined to La Grange itself: its blocks sit across 37 rate centres, named in the table below.

Where 708 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Chicagohts and Calumet Cy are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

Common questions
Where is area code 708?
Area code 708 covers La Grange, Illinois. It is not the only code there: 464 is an overlay on the same rate centres, so a La Grange, Illinois number can start with any of them.
Is a 708 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 708 the split runs 44% mobile, 44% landline and 12% VoIP, so mobile is the most likely single answer.
Which carriers hold 708 numbers?
The largest holders are T-Mobile Usa, Inc., AT&T Wireless, Onvoy. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 708 numbers are there?
The code holds 5,868 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 708 covers on the order of 5,868,000 possible numbers — most of which have never been issued to anyone.
