# Wire Virtual Account Number

> Improve customer experience and avoid returned wires when sending funds to Circle.

*Circle’s Virtual Account Number is a unique bank account number assigned to
customers. Customers use this number each time they send a wire to Circle,
allowing Circle to attribute incoming funds accordingly. Compared to previous
methods, this improves the customer experience and reduces incidents of wires
returned due to missing reference IDs.*

## Virtual Account Numbers

Circle manages a single omnibus account number for receiving all wire payments.
The way Circle identifies funds and assigns them to you is through the use of a
Virtual Account Number. This unique number enables us to properly attribute
those wired funds to you.

Each linked fiat account is assigned a unique Virtual Account Number. Any
incoming wire payment funds are attributed to the customer wallet based on the
related Virtual Account Number.

## Benefits of Virtual Account Number

When customers use Virtual Account Number to make a local Wire Payment or
Internal SWIFT transfer, they do not have to quote a tracking reference in the
payment instruction. This eliminates one of the most common reasons for wire
returns (missing or incorrect tracking reference in the incoming wire) and
thereby improves the wire payment experience and success rate.

## Payments supported by Virtual Account Number

All Domestic and International wire transfers (i.e.SWIFT payment) are supported
by Virtual Account Number.

## Affected endpoints

There is no impact to the existing API schemas. Instead we change the underlying
field value `beneficiaryBank.accountNumber` to a Virtual Account Number rather
than using Circle’s Omnibus account number. All other information i.e.
Beneficiary Bank Name, address, SWIFT code and routing number etc. will remain
unchanged.

The `beneficiaryBank.accountNumber` field is located within the response from a
successful GET request for wire deposit instructions:

* `GET: /v1/businessAccount/banks/wires/{id}/instructions`
