Use the masked phone template
Country dial-code dropdown on the left, formatted input on the right. The script formats US numbers as (XXX) XXX-XXXX and falls back to space-separated triples for international.
Form template · Basic contact form
Most contact forms ship without a phone field, then the team complains they can't follow up by call. This is the form with phone done right — country dial-code picker and auto-format.
This template is one of our free HTML form templates. See more form templates by industry.
Every template is free and fully editable in the drag-drop builder — swap fields, colors, and the button label before you publish.
No server, API route, or SDK — your Contact Form with Phone Number Field posts straight to one endpoint.
Every submission is emailed to you and saved to a searchable dashboard — spam filtered before it reaches you.
It's plain HTML you own — paste the Contact Form with Phone Number Field snippet, swap in your access key, and ship.
Copy and ship
HTML by default — the same field set also renders as React, Next.js, PHP, and cURL in your dashboard. Every variant posts to the same /api/submit endpoint. Replace YOUR_ACCESS_KEY with the key from your dashboard; that's the only edit.

To add a Contact Form with Phone Number Field to your site you need three things: a free splitforms access key, the HTML snippet above, and your key pasted into it. No backend, database, or CAPTCHA library — the form posts to one URL and every submission lands in your inbox and dashboard.
Country dial-code dropdown on the left, formatted input on the right. The script formats US numbers as (XXX) XXX-XXXX and falls back to space-separated triples for international.
The country code and the phone are submitted as separate fields ('country' and 'phone'). Your inbox gets both — concatenate them in the auto-responder template if needed.
splitforms stores the phone number exactly as typed — it does not validate or reformat it. Use the input's pattern and required attributes for basic checks in the browser, and if you need strict (libphonenumber) validation, run it in a webhook receiver before forwarding to your CRM.
What's included
Sales teams convert better when they have a phone number to dial. But poorly-built phone inputs accept any string — '+1234' or 'idk' or '(call me maybe)'. A correct phone field has a country dropdown, a numeric input mode, and a format mask that shapes the user's input as they type. The result is clean data your CRM can actually dial.

Where submissions go
Reply-to is wired to the visitor's email, so one tap on Reply answers them directly — while the built-in honeypot and automatic spam scoring filter out bots before they reach you. Every submission is emailed to your inbox and can forward to a webhook or Slack the moment a visitor hits send.

How SplitForms works
splitforms receives the submission, filters spam, saves it to your dashboard and emails you — then, on paid plans, sends it on to your webhooks and integrations. No backend infrastructure to build.

Point your form to your unique SplitForms endpoint. That's it.

We instantly capture and organize every submission in your inbox.

Send data to email, spreadsheets, CRMs, webhooks, and 7,000+ apps.

No credit card required. Set up in under 60 seconds.
Connect & automate
On paid plans, submissions can also go to Slack, Discord, Google Sheets, Notion, Airtable, Zapier or any signed webhook — and splitforms works on the platforms you build on, from WordPress and Shopify to Next.js. With Stripe connected, your forms can take payments too.

Questions
Yes — add the required attribute on the input. The form won't submit until the user types something. Combined with the type='tel' attribute, mobile keyboards open the numeric keypad automatically.
Different countries have different number lengths and formats. A US number is 10 digits; UK mobiles are 11; Indian mobiles are 10 starting with 6/7/8/9. Asking the user upfront simplifies the input mask and reduces 'why doesn't my number work' tickets.
Yes — read the country from a Cloudflare / Vercel header server-side, or use a small geolocation API client-side. Pre-select the dropdown on first load. We have a recipe in the docs.
Yes — pair with a webhook to Twilio or WhatsApp Cloud API. splitforms forwards the phone number on every submission; your downstream service handles the messaging.
