AMAZON.FIVE_DIGIT_NUMBER does not exist to capture zipcode in Amazon Alexa

Question

Alexa certification reviews say that for zip codes a slot like "AMAZON.FIVE_DIGIT_NUMBER" is used. That would make sense, but it really doesn't exist!

When I enable this type of slot, I cannot save the json intent. It gives an error: "Unknown slot type" AMAZON.FIVE_DIGIT_NUMBER "for the slot" POSTCODE ".

I can replace AMAZON.FOUR_DIGIT_NUMBER and it works fine and captures all 5 digits. However, this issue was mentioned as the reason for the failed certification.

I can replace AMAZON.NUMBER, which works (as suggested in the certification), but often captures the first 4 digits, ironically not as good as AMAZON.FOUR_DIGIT_NUMBER, which almost always captures all 5.

I want to get certified, but AMAZON.NUMBER seems to give lower results.

What should I do?

Answer 1

Yes, you received information from people of Alexa certification. There is no AMAZON.FIVE_DIGIT_NUMBER built-in slot, even in the large new series of built-in slots that they recently added.

There is AMAZON.PostalAddress and various built-in modules for cities, but none of them really suits the bill, so you are stuck with AMAZON.NUMBER.
