Every Run a Call number needs an E911 address — the physical address that 911 dispatchers reach if someone calls 911 from a device using that number.
Why this matters
If a tech in the field calls 911 from a Run a Call number — and the device they're calling from doesn't have its own GPS — 911 routes to the E911 address on file.
Get this wrong and a dispatcher sends a fire truck to the wrong house.
Setting it during number setup
When you provision a new number, Run a Call asks for the E911 address. You can't go live without it.
The address must be:
| Requirement | Detail |
|---|---|
| Physical US street address | No PO boxes. |
| USPS-validated | If the address doesn't validate, you'll get a warning and have to fix it. |
Updating an existing number's E911
If you move offices or want to reassign a number to a different location:
Open phone numbers
Settings → Phone → Numbers.
Pick the number
Then E911 address → Edit.
Enter the new address
And Save. Updates take effect within minutes.
Best practices
| Practice | Why |
|---|---|
| Use the shop's address for office-based numbers | Most calls come from the shop. |
| For per-tech numbers, use the shop address (not the tech's home) | The truck moves; the shop doesn't. |
| Update immediately when you move offices | Don't let stale addresses linger. |
Compliance notes
E911 is mandated by the FCC for any business VoIP line. Run a Call charges a small monthly E911 fee per number — passed through from the carrier.
What 911 dispatchers actually see
When a 911 call lands from a Run a Call number, the dispatcher sees:
| Field | Source |
|---|---|
| Caller's number | The Run a Call number that placed the call. |
| E911 address on file | What you configured here. |
| Call-back number | Same as caller. |
They don't see your business name or the customer's data.
