Made my life easy! Once i got the code, the embassay issued visa within a couple of hours. What more can it say?
I went directly to the consulate in Canberra. Open Monday, Wednesday and Friady 930-1300. Very friendly and helpful. I paid by Credit Card (one can also pay by EFTPOS). I got the Visa within 2 hrs upon arrival. Stamp fee is $86.

The visa section of the embassy is found round the back of the embassy on Liangmahe lu. It is open for applications on Monday 9-12 only for four day processing (but possibly also on Tuesday for eight day processing although we didn't try this out). You collect two copies of the application form from the desk and submit these with two photos. We also gave a copy of the email that you had sent us with our reference number on. This seemed to ease the process in comparison with other people applying. Visas should be ready for collection on Thursday 9-12.
It cost us 1140RMB ($157) each as British nationals for the 4 day processing, which was payable at the CITIC bank in the Capital Mansions building on Sanlitun lu. Go out of the embassy, across the bridge and it is on the left. You need to show the bank staff your passport. I don't know what the price is for other nationalities, but the Chinese applicants paid 750RMB ($100) each. Originally the embassy told us to pay 950RMB, however when we came to collect the visa they asked us to pay a further 285RMB each for the express processing, which was later reduced to 190RMB and the difference refunded to us.
There was also some confusion about when we could collect the visa. As said above, we were originally told to collect it on Thursday morning, however when we arrived at 9 we were told that it wouldn't be ready until the afternoon. Shortly later they told us to wait in the embassy, and about an hour later we received our visas without further problems.
I don't think that it is necessary for women to have their head covered when visiting the embassy or in the photos that you submit, as none of the Chinese women did. However I did (in both cases) and I think that this may have helped us receive our visas that morning rather than waiting a little longer.
I hope this information is of help to other travelers.

I waited a week to collect a visa in Beijing, but due to delay of transmission the authorization code to the embassy I gave it up.
You resend the approval again. So I collected visa without any problem Thank you very much!
I waited a week to get a visa in Beijing, but the embassy didn't receive the approval. (the embassy in Beijing's working hour is just Monday and Tuesday, from 9 to 12 o'clock, when you apply for a visa in Monday and you can collect a visa in Thursday. But if you apply for in Tuesday then you\'ll collect a visa in next week's Thursday.) So I gave it up and asked for Iranianvisa.com to resend the authorization number to the embassy in Almaty. 

The services iranianvisa.com provides worked perfectly for us.
We didn't have to travel to embassy to apply for visa and since the embassy in charge of Slovenian residents is in Vienna (in Zagreb they told us they can\'t process personal applications?) that meant a lot to us (and I reckon it was cheaper from traveling to Vienna, which you must do at least twice if you want to apply for visa yourself).
We got our authorization codes from Hamid in about a week and some days later we contacted the embassy in Zagreb where they confirmed that they have received the letter from MFA in Iran. The guy on the phone in Zagreb misinformed us about their working time (i do believe unintentionally), which according to him was until 16:00 (which is actually true, but consular hours end at 12:00). We arrived in Zagreb on Friday around two o\'clock and realized our mistake. Nevertheless, the officials at the embassy didn't send us away. We filled out forms and gave our passports and photos to the consul. They sent us to the bank to pay for the visas (by the way, we were only able to make payments in euros in Zagrebcka banka on the main square) and told us that the consul will probably not be able to make visas on this day (we didn't really count on that). Two hours later, when we returned from the bank with receipts, the visas were - to our great amazement - all ready and done.
I must again commend the personnel at the embassy for their kindness.
Embassy data: the same as stated on this page under Consulates link.
Visa fee (august 2007): 38,00 EUR per person + bank tax (about 4 EUR) Consular hours: MON-FRI, 9:00-12:00 - i am sure they will make visa ASAP but don\'t count on the same luck we had. It may take 2 or 3 days.

The service was excellent.
I found it very reassuring, that the information on the www.iranianvisa.com site seemed to be up to date, while the information on other sites was not.
I also found it reassuring that Hamid promptly replied to all email queries, because applying for an Iranian visa is very confusing.
It was very convenient to be able to carry the entire process over the internet.

To get a visa is with the service from iranianvisa pretty easy. It is clearly written in a few steps what is to do. To pick up the visa was no problem, within 2 days i got it! Good work!!
A map of the embassies would be nice...

EXTREMELY FRIENDLY PEOPLE AT THE CONSULATE BUT SLOW SERVICE TO GIVE THE VISA. OTHER IRANIAN CONSULATES DO IT IN TWO DAYS, HERE IN HONG KONG TAKES THEN BETWEEN 7 AND 14 DAYS TO DO IT.

I am very happy with the support I received from Iranian Visa. I applied through urgent process because I\'m Canadian and received my visa authorization in about a week.
The embassy I was picking up my visa from was in Dublin. The lady there had didn't seem to know what kind of agency service I was talking about, and the guy who would know wasn't there that day. I was told to ring the following day only to discover they were closed. The day after that the right guy still wasn't there, but the following morning my visa was ready for pick up, and it was for 28 days. I suspect that I was just unlucky this time so I wouldn't necessarily think the Dublin embassy was bad. So aside from just a bit of stress, no complaints!
Thank you for providing this service! Will spread the word!

Quick answering to my email questions, no problem getting my VISA. I got my code in 14 days and my VISA in 4 days at the consulate in Rome. Good service!
Consular fee was 64 euros (Rome).

I collected a visa in Almaty. The Iranian officer at the embassy is very kind . And I spent only 2 days to collect a visa.I satisfied though they issued 21 day tourist visa. But I think it can be extended in Iran if I want to stay more.
They are working from Monday to Frinday(09:30~12:30) and visa fee is 45 us Dollar.

Quick responses to emails. It would be nice to have some "hints" about places/length of time to apply for that would be likely to be accepted.
Peshawar consulate - very helpful staff, must arrive 9am to start process:
Fill out forms (x2)

Through the entire procedure of the visa application, www.iranianvisa.com - and in particular Mr. Hamid - was very, very helpful, answering any inquiry in the process immediately. Regarding the embassy issuing the visa, Mr.Ali from the embassy in Manila, Philippines, was likewise very accommodating and made it sure that I got the visa within 2 days. Please keep up the good work and thank you very much again!

At the end of the day, I managed to obtain my visa only just in time for my flight, having started the process two months earlier.  After one month I contacted Iranianvisa.com to enquire if they had forgotten me.  They replied promptly that the process was in hand.
Keep the applicant informed frequently as to the processing of the visa and give some indication of the time involved in obtaining the authorization code. After receipt of the authorization code, the experience at the embassy was fine and they took only 3 days to issue the visa.

Easy and relatively fast. very convenient to be able to pick up your visa in a nominated country.
Iranian Consulate in Damascus, very helpful. Western Villas Damascus, opening hours 8:30-12:30 Sun-Thu, though if you're there before 12:30 they will stay open until you finish youre application. 3500SP for visa, payable at the bank down the road.

Great that we still got helped quite quickly even with Ramadan
Embassy's Working hours 9-12, fee Euro 60. we received our visa within a few hour.

I found the process very easy and e-mail communication very quick. However it took much more than 10 working days and was getting worried about not receiving any feedback after that long time. But I understand that you have nothing to do with the delay, it is because of the MFA process, but i must admit i was beginning to think i will not have the visa and never hear from you again! Thank you again for everything, i will tell other travelers about your website if they want to go to Iran!The address is the same (as on www.iranianvisa.com/consulates.htm), hours are 8.30 to 11.00 from Monday to Friday.
You need to fill one form in double, 2 passport pictures, and one photocopy each of your passport page and Turkish visa page. There is a photocopy shop very close. Visa fee for Canadians is 45 euros, but it is cheaper for Europeans. You need to pay the money in the bank across the street. You leave your passport with the documents and get it back the next day with the visa in it.

The service was quick (around 10 days) and the authorization code was sent properly to the consulate in Istanbul. I am totally satisfied.
The process was quick and straightforward. It took us 1 day only and the fee for Vietnamese citizen was 40 Euros per person. Working hours are 8.30 - 11.30 AM. You need to fill the form. then go to the copy shop nearby to photocopy your documents and go to a bank across the street to pay the fee into their account. It will take around 40 minutes. So dont come too late. Bring 02 passport photos.

Very good helpful service. I'm always scheptical about online applications but nothing to worry about here. You guys delivered!
I approached the Iranian Embassy in Trabzon today, filled out the application form and was issued the visa on the spot. (after making a straightforward deposit of the appropriate fee (60 Euro) into a nearby bank).
The Staff was friendly and helpful and commented 'It takes 3 minutes, not 3 days'.

I am very happy about the services of iranianvisa.com. Everything got sorted out quickly. Highly recommended. Pall Arnason, Iceland
I collected my visa from the london consulate, Kensington court 50 London.That is in a different location than the Iran embassy, knightsbridge. If you go to the Iran embassy they will give you a piece of paper with directions to the consulate that is very helpful. walking distance 20 min.
The Iranian consulate accepts applications Mon-Fri 12:30-15:30.
It is better to show up around 12:30 in order to get the visa issued quickly.
I picked up my visa the next day at 16:00.
Though normally you collect it between 10:00 and 12:00.
To recap: It took 2 days to issue the visa.
Visa fee for Icelandic national is 11 British pounds.
I was issued a 30 day tourist visa ( single entry)

I applied for the visa on 18 Sept 07 and received the code on 22 Oct 07. Process took longer than usual due to Ramadan and embassy closures. It would be helpful if there were more realistic estimated on the webiste of the time that visa application takes. (The website says 7-10 business days, mine took over 20).
Very good value for money. Staff were helpful and knowledgeable when phoned. Thank you very much !
For UK, I joined the queue at the Iranian consulate (50 Kensington Court) at 11.45am with photos, number and completed form. I had phoned before to check that they had received the application approval from Tehran. The doors opened at 12.30 and I left at 12.45. I had to return at 4pm to collect the passport with visa stamp. Cost was ~ £88 (I paid a little extra to get the passport back on the same day). Staff were polite.

I tried to get an Iranian visa in December but at that time could only find travel agents that charged more than the price of a flight to arrange the visa. When I tried again in May I found iranianvisa.com. They did everything they said they would very quickly and efficiently and I got my visa with no problems and little expense. I will definitely use them again. The service is brilliant and I cannot think of any way it can be improved. Please keep it going and don't put up the price.
Khaley mamnoon!
