SMS API for Luxembourg: bulk SMS to +352 numbers

Luxembourg, a small European country bordered by Belgium, France, and Germany, has Luxembourg City as its capital and is a hub for finance and international institutions. Financial services, logistics companies, and government agencies often send text messages to their users. Messages are triggered by events like transaction alerts, appointment reminders, or service updates. SMS is chosen because it is universally accessible, works across borders, and is trusted for important notifications.

Number format in Luxembourg

Mobile numbers in Luxembourg have 9 digits after +352 and no trunk prefix, so the local form 628 123 456 becomes +352 628 123 456 in the to field.

Alphabet and segments

Texts in French fit 160 GSM-7 characters per segment until they use â, ê, î, ô, û, ç, ë and ï: those letters are outside GSM-7 and turn the message into Unicode at 70 characters per segment (67 per part). For short alerts, write them without those letters to keep one segment; for longer texts, the console names each letter that changed the encoding.

Time zone and timing

Luxembourg changes its clocks: Luxembourg is on UTC+1 in January and UTC+2 in July. 09:00 in Luxembourg is 08:00 UTC in January and an hour earlier in UTC while summer time runs, so give send_at with the local offset (for example +01:00 in winter) and the API does the conversion.

Send to Luxembourg with one request

The answer comes back at once with the message id, the country the number was matched to (LU) and the price. A delivered or failed event follows on your webhook, and a failed message is refunded.

For a list, send the same text to up to 10,000 numbers with POST /v1/batches, or a personal text per number in messages.

Send them in international format with the plus sign: +352 628 123 456 becomes "+352628123456" in the to field. The API also accepts spaces, dashes and a 00 prefix and cleans them, and numbers that cannot be read are listed in set_aside instead of being charged.

What language should messages use?

French and German are widely spoken, but English is also common, especially in Luxembourg City. Multilingual messages are effective.

How do I reach international visitors?

SMS works well for visitors, as it is accessible on roaming phones. Include clear instructions for non-residents.
