Can I find a postcode from an address, rather than the other way around?
Yes, you may capture full UK addresses from a postcode, or to search for a postcode/full address using part of the address. The service can be used in a website or integrated into any desktop application and is simple to set up and use.
Why would I want to use this service?
Using the Address Toolkit to validate and capture address details provides you with three main advantages. Firstly, it speeds up the process of entering addresses significantly for your operatives or customers because it cuts keystrokes by around 80%. Secondly, it makes sure that addresses in your database are in a standardised, consistent format, reducing the likelihood of duplicates. Thirdly, your database is populated with accurate addresses, so your deliveries and invoices will arrive at the correct letterbox. How often is the UK address data updated?
The Postcode Address File (PAF)®/ data is owned and maintained by Royal Mail. Daily updates (around 5000 each day) are made to ensure the information you receive is as accurate as possible.
What do the rankings returned by the DQ Toolkit API?
Each address processed has a return code to indicate the degree of match success, this ranges from 100% accurate, corrected with minor mistakes, ambiguous results (multiple matches possible with interactive review) or no match found.
Do you overwrite my existing addresses with the results of a batch cleanse?
The contact addresses used for batch cleansing will be under your control, most clients simply append the matching addresses returned into columns to the right of the addresses you currently hold. You can then simply choose which parts of your addresses you want to replace with those returned by our Address Toolkit API.
How long will my address cleansing take?
The time taken to run any address data cleanse obviously depends on the number of records in the file being cleansed, but it also depends on the quality of the data inputted. You can, however, expect your file to be cleansed at a rate of up to 100 cleanses per second, or 350,000 records an hour.
My address data is badly formatted, will the Address Toolkit API help me?
Absolutely. The Address Toolkit takes the input you provide and, after making matches, returns the results according to the Royal Mail Postcode Address File (PAF®) or International Postal Authorities reference data. This means you will always get consistently formatted results, even if there wasn’t at point of data input.
What technologies scan use to integrate the Address Toolkit API?
The API can be accessed using most development environments and from the web as: SOAP, XML over HTML or AJAX.
Can I combine UK PAF® look-up with The Address Tookit API International?
Yes. We have the ability use the international addressing service for non UK data and then switch over to Royal Mail's Postcode Address File (PAF®) data whenever a UK postcode is searched.
Can I use the API as pay per click service?
Yes, we can charge for the service on a pay-per-click basis. The advantage to this is that you can access addresses anywhere in the world using one credit pack, costing from just £50 per annum.
What benefits does the international addressing product provide?
As well as validating overseas addresses, The Address Tookit API International allows you to choose the language and format for the country in question, e.g. Cyrillic script. This means that any mailings sent to foreign addresses will be in the appropriate format and language, reducing the likelihood of misspellings or causing unnecessary offence. There are over 120 different address formats globally, and 30 different language scripts, so keeping global address data correct is no small task. The Address Tookit API International also removes the need to spell all those tricky foreign words!
