# Your address book and billing details

Your address book holds the billing addresses invoices are issued to, and the registrant details used when you register a domain. Keeping it accurate matters: an invoice takes a snapshot of the address at the moment it is raised, and registries reject domain orders whose registrant details are incomplete.

## Viewing your addresses

Open **Address Book** in the sidebar or go to `/addresses`. Each address is shown as a card, the default first, with buttons to **Make Default**, edit and **Delete**.

The default address is used automatically at checkout and on new invoices.

## Adding or editing an address

Select the button at the top of the page to open the **Add New Address** dialog, or edit an existing card. Fields marked with an asterisk are required.

| Field | What it is for |
| --- | --- |
| **Organization** | Company name. Optional, but include it if invoices must be addressed to a business. |
| **Job Title / Role** | Optional, for example *CTO*. |
| **First Name *** / **Last Name *** | The contact this address belongs to. |
| **Country *** | Chosen from your provider's list of active countries. It also decides how the phone number is validated. |
| **UK Legal Type** | Required by Nominet for .uk registrations. See below. |
| **Registrant Name** | The company or full name a .uk domain is registered to. |
| **Address Line 1 *** / **Address Line 2** | Street address. |
| **City *** | Town or city. |
| **State / Province *** | County, state or region. Required even in countries that do not normally use one — enter the county. |
| **Zip / Postal Code *** | Up to 20 characters. |
| **Email Address *** | Where invoices and registrar correspondence for this address are sent. It does not have to match your sign-in address. |
| **Phone Number *** | Validated against the selected country and stored in international format. |

Select **Save Address** when done.

### UK Legal Type values

Choose the one that describes the registrant:

- **UK Individual (IND)** and **Non-UK Individual (FIND)**
- **UK Limited Company (LTD)** and **UK Public Limited Company (PLC)**
- **UK Partnership (PTNR)** and **UK Limited Liability Partnership (LLP)**
- **UK Sole Trader (STRA)**
- **UK Registered Charity (RCHAR)**
- **Non-UK Corporation (FCORP)**
- **Other (OTHER)**

Leave both .uk fields blank if you are not registering .uk domains. See [Registering or transferring a domain](/docs/registering-or-transferring-a-domain/).

## Setting the default

Select **Make Default** on the card you want. Only one address is the default at a time — setting a new one clears the old. The default is pre-selected at checkout and used for new invoices.

## Deleting an address

Select **Delete**. You are asked to re-enter your account password first. The default address cannot be deleted — make another address the default, then delete the old one.

> **Note:** Deleting an address does not change invoices that already exist. Each invoice keeps its own copy of the address it was issued to.

## Using a different address on one order or invoice

- **At checkout** — pick a saved address from **Select Address**, or enter a new one, which is then saved to your address book.
- **On an unpaid invoice** — open the invoice and use **Change Billing Address** to switch to another saved address. Paid invoices cannot be changed.

## Troubleshooting

| Symptom | Cause and fix |
| --- | --- |
| The phone number is rejected | It is validated against the selected country. Set **Country** first, then enter the number in that country's normal format or in full international form. |
| "You cannot delete the default address." | Make another address the default, then delete this one. |
| Your country is not listed | Providers publish only the countries they trade with. Raise a ticket to ask for it to be added. |
| A .uk domain order is rejected by the registry | **UK Legal Type** or **Registrant Name** is missing or wrong on the address used for the order. Correct the address, then raise a ticket so the order can be resubmitted. |
| An invoice shows an old address | Invoices snapshot the address at the time they are raised. Change it on the invoice while it is unpaid, or update the address book so future invoices are right. |
| You cannot see an address a colleague added | Addresses belong to the billing account. Sub-accounts share the owner's address book — if it is not there, it was never saved. |
