METHOD AND SYSTEM FOR ADDRESS VERIFICATION

1 . A method, comprising:

receiving, via an application programming interface (API), a set of unverified addresses from a sender endpoint;

generating candidate address sets based on the set of unverified addresses;

determining address comparison sets from an address database based on the candidate address sets, comprising, for each candidate address of each candidate address set:

performing a first query on the address database that provides a returned address set, wherein the first query comprises an address element of the candidate address;

performing a second query on the returned address set that provides a returned address, wherein the second query comprises the candidate address; and

adding the returned address to an address comparison set for the candidate address;

determining a set of intended addresses for the set of unverified addresses based on the address comparison sets and the set of unverified addresses; and

providing the set of intended addresses to the sender endpoint via the API.

2 . The method of claim 1 , wherein generating the candidate address sets based on the set of unverified addresses comprises:

parsing the set of unverified addresses into address element sets; and

mutating the address element sets to generate the candidate address sets.

3 . The method of claim 1 , further comprising facilitating printing an asset by a print partner.

4 . The method of claim 1 , further comprising facilitating delivery of an asset to an intended address of the set of intended addresses by a mail partner.

5 . The method of claim 1 , wherein the candidate address set comprises undeliverable addresses.

6 . The method of claim 1 , further comprising:

ingesting, by an address entry component, the unverified address in a single action from a sender; and

in response to the single action, sending the unverified address to the API.

7 . The method of claim 6 , wherein the address entry component comprises a user interface configured to receive input in at least one of freeform text or a set of address element fields.

8 . The method of claim 1 , further comprising receiving a notification from a mail partner;

and updating the address database based on the notification.

9 . The method of claim 1 , wherein the set of unverified addresses is received as a CSV file uploaded to the API.

10 . The method of claim 1 , further comprising determining a set of deliverability confidence scores for the set of intended addresses, wherein the set of deliverability scores are provided to the sender endpoint via the API.

11 . A system, comprising:

a processing system configured to:

receive, via an application programming interface (API), an unverified address from a sender endpoint;

generate a candidate address set based on the unverified address;

determine an address comparison set from an address database based on the candidate address set, comprising:

performing a first query on the address database that provides a returned address set, wherein the first query comprises an address element of a candidate address of a candidate address set; and

performing a second query on the returned address set that provides a primary number, wherein the second query comprises a candidate address of the candidate address set;

determine an intended address based on the address comparison set and the unverified address; and

provide the intended address to the sender endpoint via the API.

12 . The system of claim 11 , wherein the unverified address is received as part of a batch of unverified addresses.

13 . The system of claim 12 , wherein the batch of unverified addresses is processed by the system in parallel.

14 . The system of claim 11 , wherein a physical asset is delivered to the intended address.

15 . The system of claim 11 , wherein the address comparison set comprises deliverable addresses.

16 . The system of claim 11 , further comprising an address entry component, configured to:

ingest the unverified address in a single action from a sender; and

in response to the single action, send the unverified address to the API.

17 . The system of claim 16 , wherein the address entry component comprises an upload interface.

18 . The system of claim 11 , wherein the intended address is selected based on a similarity score between each address of the address comparison set and the unverified address.

19 . The system of claim 11 , wherein receiving the unverified address comprises retrieving the unverified address from an external database via the API.

20 . The system of claim 11 , wherein the processing system is further configured to determine a deliverability class for at least one of the unverified address or the intended address, wherein the deliverability class is provided to the sender endpoint using the API.
