Reachability
All major call types are supported for Latvia, with both inbound and outbound calls available across domestic, international, and toll-free number categories.
| Call type | Inbound | Outbound |
|---|---|---|
| Domestic | Supported | Supported |
| International | Supported | Supported |
| Toll-free | Supported | Supported |
Domestic outbound: A local Latvia phone number is required to place domestic outbound calls. Verified caller ID for domestic outbound is best effort and not guaranteed.
Caller ID
| Call type | Inbound format | Outbound format |
|---|---|---|
| Domestic | +E.164 | Local (non-guaranteed) |
| International | +E.164 (non-guaranteed) | +E.164 |
| Toll-free | +E.164 | Local (non-guaranteed) |
Inbound caller ID for international calls is delivered in +E.164 format but may not always be present. Outbound caller ID for domestic and toll-free calls is presented in local format, though delivery is not guaranteed by the carrier network.
DTMF support
DTMF (dual-tone multi-frequency) signaling uses RFC 2833 format for both inbound and outbound calls in Latvia.
Emergency services
Calling emergency services numbers in Latvia is not supported. Implementations must not rely on voice calling for emergency service access. Users should be directed to use a standard telephone line or mobile device for emergency calls.
Compliance note
These guidelines summarize carrier requirements at the time of publication and do not constitute legal counsel. Verify that your implementation complies with all applicable telecommunications regulations in Latvia.
