Address lookup

When to use​

Use an address lookup when you’re asking users for an address within the Bristol City Council (BCC) area. It asks users to enter the postcode and choose from a list of street addresses.

When not to use​

As this address lookup only works for Bristol City Council area addresses, use a manual option such as text inputs or a textarea when you're collecting other UK or international addresses.

Step one​

This is the default state.

Find your postcode on royalmail.com
<section class="address-lookup-block">
  <div class="field field--postcode">
    <div class="bcc-form-question">
      <label for="postcode" class="field__label field__label--block"
        >Postcode</label
      >
    </div>
    <div class="bcc-form-answer">
      <input
        aria-describedby="postcode-error"
        id="postcode"
        name="postcode"
        class="field__input"
        type="text"
        value=""
      />
      <button type="submit" class="button secondary">Find address</button>
    </div>
    <h6 class="field__message">
      Find your postcode on
      <a href="https://www.royalmail.com/find-a-postcode">royalmail.com</a>
    </h6>
  </div>
</section>

You should allow users to enter their postcode:

  • in upper or lower case
  • without spaces or with additional spaces at the beginning, middle or end

This is better for the user than rejecting the input and telling them they have entered an invalid postcode.

Step two​

A postcode has been entered. Now the user can select an address.

<section class="address-lookup-block">
  <div class="field field--postcode">

Your selected address

2 Baldwin Street Bristol BS1 1SA

<div class="field field--postcode">
  <div class="bcc-form-question">
    <label for="postcode" class="field__label field__label--block"
      >Postcode</label

      >Tell us your address isn't listed</a
    >
  </h6>
</div>
<div class="info info--affirm info--reverse">
  <h4>Your selected address</h4>
  <h2>2 Baldwin Street Bristol BS1 1SA</h2>
</div>

This step includes a link for users to tell BCC that an address is not listed.

Error messages​

Display an error when there's a problem.

Make sure:

  • The form control has the aria-describedby attribute and references an associated error message
  • The associated error message has a unique ID
