The 933 service is a courtesy text-to-speech service that Bandwidth offers as part of our 911 package. It’s intended to be used during the onboarding process to test connectivity to the emergency IPs for the 911 service prior to making live 911 calls. When an end user dials 933, it'll read back the phone number and address that's provisioned in the portal. 

Note: Although the 933 service is available anytime (please limit to 1 call per minute), it isn't meant to be used as a fully functional address verification service. To verify the full address, it's best to check the provisioned address directly in the portal or via the API call. If there is a port in progress, always test 933 after the port completes (even if the address was pre-provisioned before porting).

When you make a 933 call, the service will read back the number you’re calling from and the address that was provisioned for that number. If the address read-back isn’t the one you want to be provisioned for that endpoint, please update the appropriate endpoint or modify the associated geolocation.

A 933 call result with an error code indicates there’s an issue that has prevented the location from being provisioned. Depending on the issue, the readback message may provide additional details to help identify the root cause. The 933 readback messages are also available via email notifications.

Explanation 

Provisioned

“You have reached the 911 Address Validation Service. You are calling from [1+number]. Your 911 address is [text-to-speech of Address_Line_1, Address_Line_2, City, State, Zip, CountryCode]. Your 911 service is active.”

The phone was correctly installed and the 911 information was properly provisioned. No further action is needed. 

Unprovisioned

"You have reached the 911 Address Validation Service. You are calling from [1+number]. There is no record found matching this telephone number. The 911 PSAP routing service for the number you are calling from is not active, and a 911 call would be routed to the national Emergency Call Center. Please contact your service provider immediately to configure your 911 service. Reference code 1A.

The phone number wasn’t found because no endpoint record exists for it. You need to add the endpoint to your 911 account. 

Unprovisioned

“You have reached the 911 Address Validation Service. You are calling from [1+number]. There is no 911 address configured for this telephone number. The 911 PSAP routing service for the number you are calling from is not active, and a 911 call would be routed to the national Emergency Call Center. Please contact your service provider immediately to configure your 911 service. Reference code 1B.

The phone number was found but the address is completely unprovisioned (missing/blank). While the number is in your 911 account, there’s no provisioned or valid address associated with it. You need to update the address for this endpoint

“You have made a test emergency call. The callback number associated with your service is [1+number]. The address for this test call is [text-to-speech of Address_Line_1, Address_Line_2, City, State, Zip, CountryCode]. Your 911 service is active.”

The phone was correctly installed and the 911 information was properly provisioned. No further action is needed.

“You have made a test emergency call providing latitude-longitude. The callback number associated with your service is [1+number]. The nearest estimated address for this test call is [text-to-speech of Address_Line_1, Address_Line_2, City, State, Zip, CountryCode]. Your 911 service is active.”

Alternate End User Identifier (AEUI) was found, a Geolocation record has been provided as an X-Y, and a callback number has been supplied. The X-Y successfully converts to a civic address. No further action is needed. 



Provisioned

“You have made a test emergency call providing latitude-longitude. The callback number associated with your service is [1+number]. The provided latitude-longitude is [digits]. This latitude-longitude cannot be converted to an address. Your 911 service is active."

AEUI was found, a Geolocation record has been provided as an X-Y, and a callback number has been supplied. The X-Y doesn’t successfully convert to a civic address but is still in the USA-Canada polygon and can be processed. No further action is needed.
