\# Stores and POS The \*\*Stores\*\* and \*\*POS (Point of Sale)\*\* are critical for receiving in-store payments with QR. They allow creating your store and assign its points of sale. !\[POS and Stores\](https://www.mercadopago.com.ar/images/mobile/stores\_pos-v1.es.png) ## Stores \*Physical store\*\* where your customers can acquire products and services. You can have multiple stores in the same account. ### Benefits The benefits of creating stores are: - \*\*Ensure traceability\*\*. Each payment shall be associated with a specific store, and when obtaining your reconciliation reports, it will be valuable to identify transactions by store. - \*\*Map Visibility\*\*. The created stores appear on the Mercado Pago or Mercado Libre App's map as they receive payments. Thus, customers can easily find them. - \*\*Improve Stores and POS organization\*\*. ## Create a store It is relevant to declare the store name, working hours, location, and an identification reference to create a new store. Go to \[Create store\](https://www.mercadopago.com.ar/developers/en/reference/in-person-payments/qr-code/stores/create-store/post) in our API Reference to create a new store. There you will find all the necessary information. > WARNING > > Important > > 1\. You should know the \`country\_id\` of your current location at \[our countries API.\](https://api.mercadolibre.com/countries) > 2\. The \`state\_name\` has to match the \*\*states\*\* of \[the specific country.\](https://api.mercadolibre.com/countries/$country\_id) > 3\. The \`city\_name\` must match the \*\*cities\*\* of \[the states.\](https://api.mercadolibre.com/states/$state\_id) # Point of Sale (POS) It is a \*\*point of sale\*\* that exists in a branch or physical store. Each POS will be linked to a unique QR code. ### Create POS Having your stores set, you can create your Point of Sale. Consider the following: | Term | Description | | --- | --- | | \`EXTERNAL\_STORE\_ID\` | Links the POS to the store. It is a mandatory field and matches the \`external\_id\` of the previously created store. | | \`EXTERNAL\_ID\` | Identifies each Point of Sale (POS). It is required and can not be modified nor repeated on the same Mercado Pago account. You may also find it as \`EXTERNAL\_POS\_ID\`. | Go to \[Create POS\](https://www.mercadopago.com.ar/developers/en/reference/in-person-payments/qr-code/pos/create-pos/post) in our API Reference to create a POS. There you will find all the necessary information. > NOTE > > Note > > After the Point of Sale creation, you will see the QR files in the \`Response\` section, with other relevant data.
