Dimension Data Contact Details

To contact Dimension Data, call +27 11 575 0000 (NTT DATA Middle East & Africa headquarters switchboard).

The Dimension Data South Africa contact number is +27 11 575 0000, the switchboard of NTT DATA’s Middle East and Africa headquarters in Bryanston, Sandton. Dimension Data now operates as NTT DATA: the dimensiondata.com website redirects to NTT DATA’s services site, services.global.ntt, and the Dimension Data brand no longer has its own website.

The South African operation appears on NTT DATA’s site as the “Middle East & Africa headquarters (South Africa)”. It is not the same as NTT Global Data Centers’ Johannesburg 1 facility, which is a separate data-centre site.

Official contact channels

Call the Bryanston switchboard on +27 11 575 0000 (011 575 0000 from within South Africa). This is the number NTT DATA lists for its Middle East and Africa headquarters.

For business sales and service enquiries, NTT DATA runs a South Africa version of its website (the en-za locale) with a “Speak to our experts” enquiry form at services.global.ntt/en-za/speak-to-our-experts. The old South African contact-us address on the NTT site now redirects to this form.

NTT DATA’s global headquarters is in London, so South African callers should use the Bryanston number rather than the London office.

What Dimension Data (NTT DATA) provides

Dimension Data’s former website now leads to NTT DATA’s services site, which takes business sales and service enquiries through its “Speak to our experts” form. The South African office in Bryanston serves as NTT DATA’s headquarters for the Middle East and Africa region. The exact name of the South African legal entity was not readable on NTT DATA’s company information page, so check it on your contract or invoice if you need it.
