Panama’s national postal authority “Correos Panamá” has officially launched a postal code system, available at the official government portal: 
https://codigospostalespanama.gob.pa/
The official format is alphanumeric: K3MD7-64B34 (5 alphanumeric characters + dash + 5 alphanumeric characters)
Shopify’s checkout currently rejects this format for Panama (country code: PA), preventing customers from entering a valid, government-issued postal code.
Requested action: Update the postal code validation pattern for Panama ¶ to accept this format.
Suggested regex: ^[A-Z0-9]{5}-[A-Z0-9]{5}$
Supporting evidence:
-
Official portal: https://codigospostalespanama.gob.pa/
-
Shopify currently shows a validation error when entering codes in this format at checkout
