Remove restricted GTIN

Google is not accepting restricted GTIN.

What Google says:

Item uses a restricted GTIN

What's the problem?

You submitted a value for the 'gtin' attribute that's in the restricted range (starts with 2, 02, 04), instead of a globally valid value.     Restricted range GTINs are only intended for use with internal systems and not for sharing externally. Learn more about unique product identifiers.

Why should you fix this?

A correct, globally valid value submitted through the 'gtin' attribute helps us understand exactly what you're selling. When we understand what you're selling, we can help boost your ad's performance by adding valuable details about the product and serving the ad in a more relevant way to users.

To remove the restricted GTIN from your feed, use the preg replace box with this code: #^(02|05|04|2|99).*#
