Verifying UK address - best way

markb · Jan 21, 2016

I run a UK website where people signup and enter their home address. They currently verify their account using their email address but am interested in verifying that they actually live in the address they have given.

What do you think would be the easiest/best/quickest method of checking this?

I was thinking about 2 options :

1) use PayPal to charge a small fee, and then take the address from PayPal and check it is the same as the one given when they signed up. Benefit of this is that it is quick/instant.

2) somehow send them a pin via post that they need to enter on the website to verify their account. Problem is this would probably be costly and slow.

Anyone got any better ideas?

Thanks

You could use http://www.whitepages.co.uk/electoral-roll-search-and-electoral-register-voters.html to validate some surely?

Some companies still use the PIN/Password verification via post to confirm this, so it is a method that works. I don't think Paypal validate by post address (may be wrong), so it could equally be fake on there too.

I think when google used postcard verification for google local, the legend goes...they started dumping bags of mail outside the office of the person who came up with the idea.

I think if telephone verification won't work, the paypal idea is quite elegant it's another step so might lose some customers on the way.

Take a credit card payment, and match the credit card address to the stated home address.

Of course, that depends on what you're offering by registering being "worth" paying something for.

Doesn't work unless the customer has a numeric first line of their address though.

The question is how far you want to "prove" that somebody is who they say they are. If all you're asking for is an address, then somebody could give you a random address that they find on a website (for example)

But if you're actually charging a fee of some kind at the same time, that's an extra layer of verification since it's highly likely they're using their own credit card (whether personal or corporate) unless what you are getting people to sign up for is so valuable that they're willing to use stolen credit card details to access it!

Are you looking for verification that the address is valid or a cross check to make sure that person actually lives there ?

If its the first one there is plenty of API's available for address validation for example :

US

Not looked into it but you might be able to cross check somewhere to achieve what you need.

The service would be worth paying a small fee for the users. Just to clarify, they signup with a home address, but I want to make sure that the address is where they live, so my original idea was use PayPal/credit card to charge them a fee, then take the address from PayPal/credit card so we know their correct address.

Even then it is only a "fuzzy" logic check with many banks, as I understand it, so it may pass even if you have a numeral in the first line of the address and it does not match that entered.

The AVS checks first line for any leading numeric characters, and the numeric portion only of the post code. I can pass an AVS check for any address within my town, surrounding villages and a few large industrial estates, as they all have the same numeric portion of the post code!

Near impossible to do with 100% certainty.

Electrical roll isn't complete, as people can opt out of the published version.
Cards can be registered elsewhere, as can PayPal addresses. For example, you can use your work address as a PayPal one.

Your best bet is to do like Nominet do, and others have suggested in this thread, and verify the address they have entered. There are loads of services that do this.

This is what you have to do to comply with anti money laundering regs if your industry is affected, so is probably the best way.

There are companies out there who can do it for £2-3 if you're delivering volume.

You do need client permission to run this check though.

Yep, AVS is flaky at best

ScanMyPost require proof of address via statements/bills/passport/etc, so their system is invasive but I guess solid.

Its for a free classifieds website like gumtree. People need to register on the site and before they can create an advert, they need to enter their name, address and postcode. What I want to do is to verify that the person who is registering is who they say they are and that they live at the address entered.

Ideally I am looking for an instant online verification method, so they can create their advert on the site straight away. I don't really want there to be a long delay.

Easy if you're willing to pay for it

markb · Mar 14, 2016

I am willing to pay for the service but would need to easily pass the cost on to the person using our website. We have around 2,000 new users registering every day, so the cost would be too expensive for us if it was costing £2 to 3 per user.

Has anyone else got any suggestions which would work. I was thinking charge a small fee via paypal to each user and then check the address returned by paypal to the address they used to register on our site and if they match then let them use the site, otherwise reject it.

Thanks

Why do you need too verify address ?

As mentioned I want to make sure when someone registers to use the website I want to confirm the address they use is the one they live at so they don't provide false information.

I also want to prevent people from registering multiple accounts using false details which is what they can do now. I thought if I verify their name and address on their account, I.e. I verify they are who they say they are, then it will stop people creating lots of fake accounts.

Maybe someone has a better idea and solution to prevent this?
