How can I configure TXT records that are longer than 255 characters in Route 53?

Short description

A TXT record has the following limits:

• One or more strings that are enclosed in double quotation marks (")
• A value of up to 255 characters in one string
• Multiple strings of 255 characters in a single TXT record
• Maximum length of a value of 4,000 characters
• Case-sensitive values

Note: In the console, the value on a separate line is treated as a different record value.

Resolution

To break the value into a string of up to 255 characters, enclose each string in double quotations marks ("). For example, use the "String_1 " "String_2 " "String_3" value.

Note: For the value format, you must separate the values with a space and keep all the strings on the same line.

The following example query shows a TXT record configures values for domain verification, the SPF record, and DomainKeys Identified Mail (DKIM) signing:

txt1.geeksbox.club. TXT 3600 "google-site-verification=rXOxyZounnZasA8Z7oaD3c14JdjS9aKSWvsR1EbUSIQ"
"v=spf1 include:_netblocks.google.com " "include:_netblocks2.google.com " "include:_netblocks3.google.com ~all"
"spf2.0/pra include:spf1.amazon.com include:spf2.amazon.com include:amazonses.com -all"
"v=DKIM1;k=rsa;p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDeIhtCv3vUinyhKiKtZ8efjHGGo8gE1T+o7gLrvo6yRtdz9ICe6Fz5sgz0WYFW5nCV4DmaTcS25TfgWKsLgg"

Note: It's a best practice to create a TXT record that contains the applicable values instead of a Sender Policy Framework (SPF) record. For more information, see Why don't other mail providers identify the SPF record I successfully created in Route 53?
