How to connect a Squarespace Domains domain to Vercel

The exact records to add at Squarespace Domains, written the way its form asks for them, for both www and the bare domain.

Checked 16 October 2026

In short

The records you'll add

Type
A
Name
Data

Most projects; newer ones may show a different address on the domain card

Type
CNAME
Name
Data

Replace the capitals with your own value from the host's dashboard.

Each project gets its own CNAME target: copy it from the domain card

Step by step

Set it up

  1. 1

    Add the domain in Vercel first

    In Vercel, go to Project→Settings→Domains→Add and enter your domain (for example www.example.com). Add the bare domain and www separately, then set one to redirect to the other in the project's domain settings.

    Vercel shows the exact A address and CNAME target for your project on the domain card. Use those values if they differ from the ones here.

    Custom domains are included on the free plan.

  2. 2

    Open the DNS records at Squarespace Domains

    Sign in, then go to Domains→your domain→DNS→DNS Settings→Custom Records

    The domain has to use Squarespace's nameservers (Nameserver Connect).

  3. 3

    Clear what's in the way

    Domains come with a "Squarespace Defaults" group that points the domain at a Squarespace site. Delete it (the trash icon next to Squarespace Defaults) if the domain is moving away from Squarespace.

  4. 4

    Add the record for www

    Click Add record and add:

    Type
    CNAME
    Name
    Data

    Replace the capitals with your own value from the host's dashboard.

    Each project gets its own CNAME target: copy it from the domain card

  5. 5

    Point the bare domain

    Vercel gives fixed addresses for the bare domain, added as A records.

    Type
    A
    Name
    Data

    Most projects; newer ones may show a different address on the domain card

  6. 6

    Wait, then check

    Changes at Squarespace Domains take effect within 48 hours. Once Vercel sees the records, it issues the certificate for https by itself. Use the check below to see what the world sees.

Check your domain

Once the records are in, see whether the world can see them pointing at Vercel.

Changes can take from a few minutes to a day to show up everywhere.

Good to know

Common snags

  • If you have a CAA record, it must allow Let's Encrypt.
  • To add an ALIAS record, first turn off DNS Security Extensions under DNS, then DNSSEC.
  • Squarespace asks for your password again before adding a record.
  • A CNAME can't use @ as its name.

Questions

Before you start

Should I use www or the bare domain with Vercel?

Add the bare domain and www separately, then set one to redirect to the other in the project's domain settings. www always works with a single CNAME; the bare domain depends on what Squarespace Domains offers, covered in step 5.

Why does my site show a certificate error?

The certificate is issued once Vercel sees your records, which can take a while after DNS changes. If it stays, check for old records on the same name (parking pages, AAAA records) and, at Cloudflare, that the record is set to DNS only.

Will this affect my email?

No. Email uses MX records, which these steps don't touch. Only change the records for @ and www.

Rather skip git and build settings?
