Steps to Generate GTIN

The steps to generate GTIN are given as below.

  1. Register with GS1 India

In case you want to sell your products or services through online platform then you can issue a request to GS1 India for allocation of GTIN. In fact, once you are registered with GS1 India or any other authorised GS1 organisation, you can create any of the GS1 ID keys using your subscription number.

GS1 India is the only authorised body in India to allocate these barcode numbers. If you are not registered yet, the first step is registering with GS1 India.

For registration, fill an online form by visiting GS1 India website.

While filling the form, it is important to carefully select the ‘number of product barcodes’ based on your both current and future requirements for barcode numbers. This is because when any change occurs to your product (in net content, ingredients, pack size, etc.) or new one gets introduced (promotional variants/new products), you would require to change the barcode number on the same.

This must be taken into account while deciding for the barcode number capacity since it’s not possible to upgrade the selected capacity after registration. In such cases, you would need to apply a fresh registration by paying the applicable registration and annual fee at that time

The GTINs are available in batches of 100, 1000, 10,000 and 100,000.

After filling the required details and attaching required company documents, pay the required fees using payment options. Once this process is completed, your will receive your barcode subscription allotment letter in 4-7 working days.

  1. Login to DataKart

    • Use the credentials given in your GTIN allocation letter to log in to DataKart portal.

  • After logging in to DataKart, click on ‘Create Product Data’ icon on your DataKart home.

  • ‘Create Product Data’ screen will appear, with GTIN as prefilled value and different product attributes as blank fields. You may take a note of this GTIN.

  1. Get GTIN

To assign GTIN number allocated to your product, add the product attributes and hit ‘Save & Publish’ towards the end.

In DataKart, you may either add data of product individually or in bulk. If you have large number of products you can download an excel template, put the details in the template and upload the same.

Once done, GTIN numbers get allocated to your products.
