New KYC guide COSS.IO

This guide serves as a checklist before submitting your documents.

There are 4 components in your KYC application:

  1. Proof of Identity ( any submitted documents with an expiry date has to be more than 6 months from the date of submission. Do note that this only applies for documents with expiry dates )
  2. Proof of Address (cannot be half page)
  3. A Selfie
  4. The data fields you input in COSS website itself

This guide will walk you through the requirements for each component.

Below you will find the requirements for each component:

Proof of Identity

We accept Passports and Government Issued Photo-IDs. We recommend International passports, as compared to some Government Issued Photo-IDs, because passports contain all the data fields we require.

These are the fields that MUST be present for a valid proof of identity :

  • Name
  • Nationality
  • Date of Birth

Proof of Address

As explained in previous articles, we only accept the following for proof of address:

  • Bank Statements issued within 3 months of application (most preferred) 
    (Latin Characters are allowed as long as your Proof of Address specifies your name, legal residential address, and date of issue.)


  • Utility Bills (water/gas/electricity) issued within 3 months of application(most preferred)
    (Latin Characters are allowed as long as your Proof of Address specifies your name, legal residential address, and date of issue.)


  • A tax assessment issued within the year


  • Tenancy contracts issued within the year with the legal name of the customer, a residential address, a date of issue, and lastly, your signature alongside the landlord’s signature


  • Government Correspondence (subject to our satisfaction)

Please do NOT submit internet OR mobile/landline phone bills (No telecommunication bills of any kind).

We do not accept any handwritten documents.

Screenshots/Print screens are allowed AS LONG AS we can verify your full name, address and date of issue.

Full page of the documents must be visible ; cropped documents will be rejected.

Tax assessments, tenancy contracts and letters from recognized public authorities have to be translated into English.

You can censor your bank account number and your balance.

Here is another example:

A Selfie

1) Your head must face the camera directly with full face in view

2) You must have a neutral facial expression or a natural smile, with both eyes open

3) Taken in clothing that you normally wear on a daily basis

4) Taken within the last 6 months

5) Use a plain white or off-white background

6) Taken with your proof of identity AND a piece of paper that clearly shows your name, date, and written on it.

The following illustrations show the correct example and some unacceptable examples.

We accept JPG, GIF, PNG, TIFF or PDF formats. Please try to keep the file size below 1 MB.

Data Fields in KYC section

Be careful when inputting your information into the KYC section of our website.

As long as the information matches word for word as what is reflected in your Proof of Identity or Proof of Address document, you are good to go.

IF your identification documents (Passport / Government issued Photo-IDs) contain any alias (e.g., John Doe AKA JD), then you should have “JD’ in the Alias field. Otherwise, if you DO NOT have an alias, please leave it empty.

You are required to fill in your full address. We have to have the exact matching details for your verification.

Your KYC documents will be subjected to assessment by our Compliance team who will at its own discretion either approve or reject your application. 

In the event of rejection, we will make efforts to reach out to you stating the reason for rejection and suggest ways to amend your application.

US citizens

We will continue to onboard new users from the US.

Until FATCA is implemented, you will still be able to trade Crypto to Crypto on COSS.IO.

You will still be subjected to mandatory KYC according to the new guidelines.

By the US, we mean US citizens AND US residents. If you are a US citizen or resident, you will not be able to trade FIAT until FATCA reporting is fully implemented.

Once FATCA is implemented, the option to trade FIAT will be open to you, and no new submission of documents will be required.
