Ideal Postcode provides UK address lookup and validation services. PolyAI’s integration enables voice agents to help callers find and confirm their address using just a postcode.
This is a managed integration. Prepare the credentials below, then contact your PolyAI account manager to complete setup.

Capabilities

  • Postcode lookup: Retrieve all addresses associated with a UK postcode
  • Address selection: Help callers identify their specific address from results
  • Address validation: Confirm address details during booking or registration flows

Getting started

Prerequisites

  • An Ideal Postcode account with API credits
  • Your API key
  • PolyAI project access

Step 1: Obtain API key

  1. Log in to your Ideal Postcode Dashboard
  2. Navigate to API Keys
  3. Copy your API key (or create a new one for the PolyAI integration)

Step 2: Configure usage limits (optional)

You can set usage limits and IP restrictions on your API key for additional security:
  1. Go to API Keys → Edit
  2. Set daily/monthly lookup limits
  3. Add IP allowlists if required

Step 3: Provide credentials to PolyAI

Share your API key with your PolyAI account manager. It will be stored securely.

How it works

Typical conversation flow:
  1. Agent: “Can I take your postcode?”
  2. Caller: “SW1A 1AA”
  3. Agent: “I found several addresses at that postcode. Is it number 10 Downing Street?”
  4. Caller: “Yes, that’s correct.”
  5. Agent: “Perfect, I’ve confirmed your address as 10 Downing Street, London, SW1A 1AA.”

Use cases

  • Booking confirmations: Verify delivery or service addresses
  • Account registration: Capture accurate address details for new customers
  • Address updates: Help existing customers update their address on file

Limitations

  • UK only: Ideal Postcode covers UK addresses only; use alternative providers for international addresses
  • Credit-based: Each lookup consumes API credits; monitor usage to avoid service interruption
  • Multiple addresses: Some postcodes have many addresses; the agent may need to narrow down results
