Adding DID numbers means either claiming new ones from Amazon Connect''s pool or porting existing ones from a carrier. Both flows happen in the Amazon Connect console accessible from Service Cloud Voice.

  1. Open the Amazon Connect Phone Numbers page

    In Service Cloud Voice, open the Amazon Connect console. Navigate to Routing, then Phone Numbers.

  2. Claim a new number

    Click Claim a number. Select the country, the type (DID local, DID toll-free, UIFN), and pick from the available numbers. Confirm the claim; the number is yours within minutes.

  3. Port an existing number (alternative)

    Click Port a number to bring in an existing DID. Complete the porting form: current carrier, account number, billing address, Letter of Authorization. Amazon Connect coordinates with your current carrier; expect 2 to 4 weeks for the port to complete.

  4. Assign the number to a Contact Flow

    Once claimed or ported, edit the number and pick a Contact Flow. Incoming calls to this number will enter that flow, which can read the DNIS (the number itself) and branch routing accordingly.

  5. Test the inbound flow

    Call the number from a personal phone. Confirm the call hits the right Contact Flow and routes to the expected queue. Watch the Salesforce screen pop for any agent that picks up.

  6. Track the number in Salesforce analytics

    Build a Salesforce report on the VoiceCall object filtered by DialedNumber. Per-DID call volume and outcomes appear here; use them for campaign attribution and capacity planning.

Key options
DID Localremember

Local phone numbers from a specific country and area. Per-call minutes billed to the calling party.

DID Toll-Freeremember

1-800, 1-888, 1-877 numbers. Per-call minutes billed to the receiving party (your org).

UIFN (Universal International Free Number)remember

International toll-free numbers (00800 prefix). Cross-border free for the caller.

Ported numberremember

An existing DID brought into Amazon Connect from another carrier. Preserves your published number through the transition.

Gotchas
  • DID porting takes weeks. Plan the cutover carefully; published numbers cannot ring through during the brief porting window.
  • Toll-free numbers are billed per minute received. High-volume support lines can incur significant cost on toll-free that local DID would avoid.
  • Number portability requirements vary by country. Porting numbers internationally has more constraints than within one country.
  • Amazon Connect number pools are not unlimited. Specialty area codes or vanity numbers may not be available; check before promising a specific number.
