Update Contact Page Phone Number

I need the phone number shown on the Contact page of my website replaced with a new one. The job is straightforward:

• Locate every instance of the current number on that page—including visible text, tel: links, and any hidden meta or schema markup.
• Replace it with the new number I provide.
• Test on desktop and mobile to confirm the change displays correctly and the click-to-call link works.
• Leave all styling, layout, and other content untouched.

I’ll supply the new number and give you access to the site’s CMS or code repository as soon as we start. A quick, clean update and a brief confirmation that everything looks good is all I’m after.
