Which Missouri area codes share coverage?

NANPA groups these codes in shared numbering complexes: 235 / 573; 314 / 557; 816 / 975. Members can serve overlapping areas; being in the same complex does not necessarily mean identical geographic boundaries.

How do I dial a number in Missouri?

Open the individual area code to check its local dialing rule. For a phone lookup, enter +1 followed by the three-digit area code and the seven-digit number. A state or area code alone is not enough to look up a particular number.

Does an area code from Missouri show where the caller is?

No. An area code describes a number’s assigned region. People can keep numbers after moving, use them while traveling, or place internet-based calls. Caller ID can also be spoofed, so the code does not confirm the caller’s location or identity.
