Legacy Edge Location IDs
Twilio previously used short region-style IDs (e.g., ie1, au1, us2) to identify Edge Locations in FQDNs, SDK parameters, and SIP URIs. These have been replaced by descriptive Edge Location names (e.g., dublin, sydney, umatilla).
Action Required by April 28, 2026
The api.REGION.twilio.com domain pattern (e.g., api.ie1.twilio.com) will stop working on April 28, 2026. This applies to REST API domains only. See the API Domain Migration Guide for migration instructions.
Warning
ie1 and au1 are still valid as processing Region identifiers (e.g., api.dublin.ie1.twilio.com). Only their use as edge location selectors in the old api.REGION.twilio.com pattern is deprecated.
| Legacy ID | Location | Current Edge Location name | Example: old (deprecated) | Example: current |

us1 | US East Coast (Virginia) | ashburn | api.us1.twilio.com | api.twilio.com |
us2 | US West Coast (Oregon) | umatilla | api.us2.twilio.com | api.twilio.com |
gll | Global Low Latency | roaming | — | — |
Info
The "current" column shows the correct hostname for data processing in that region. Regions without a dedicated processing region (br1, de1, jp1, sg1, us2) process in US1 — use api.twilio.com.
